To build a pair of speakers, you will need:

1. A speaker enclosure or cabinet
2. Speaker drivers (woofer, tweeter, and possibly a mid-range driver)
3. Speaker wire
4. Wire stripper
5. Screwdriver
6. Soldering iron (optional)

You may also need other materials depending on the specific design of your speakers, such as:

1. Wood or other materials to build the enclosure
2. Glue or screws to hold the enclosure together
3. Grills or covers to protect the drivers
4. Gasket material to seal the enclosure
5. Varnish or other finish to protect the wood

Depending on your level of expertise, you may also need additional tools such as a saw, drill, and sandpaper.
